This new solar-powered wireless keyboard is almost perfect. It works great, but it has some perfectly annoying “features.”

There is no printed manual or full set of Internet instructions. Its web site is incomplete. No built-in indent on the keyboard is provided for storage and travel with its USB dongle. There is no way to know when the caps lock key is activated.

Aside from those four minuses, Logitech has done a stellar job with engineering and design of its new Wireless Solar Keyboard K750 for Mac. Solar and ambient light battery charging are effortless. So is power management using a free software download. Battery efficiency is exceptional.
